Update: And it's official, folks.

Some new pricing and launch date info on the LG G-Slate for T-Mobile has emerged, just a couple days away from its expected in-store availability. The highly anticipated tablet from T-Mobile and LG will cost you $529.99 on contract after a $100 mail in rebate and $749.99 at full retail price. The tablet is set to hit stores this Wednesday, April 20. That $529.99 pricing is the same number we saw a few weeks ago. Not surprising, but this is also the same day as the T-Mobile event coming up this Wednseday night in New York City (we'll be there!).

But the new G-Slate isn't the only new Android powered device we'll see this Wednesday. The G2X, T-Mobile's first dual-core powered phone, and the Sidekick 4G will also launch this Wednesday. The Sidekick on contrant will set you back $99.99 after a $50 mail in rebate on a new two year contract. If you don't want to do the contract thing, the phone will cost you $379.99. As for the G2X, the 3D powered cell phone on contract will be $199.99 after a $50 mail in rebate. And again, if you don't do the contract thing, it's gonna cost you $499.99. Whooo... okay, now who's getting what this Wednesday? [TmoNews]
